DEVICE AND METHOD TO IMPROVE PERFORMANCE OF MOTOR VEHICLE

摘要

FIELD: transport.SUBSTANCE: invention can be used in vehicles (V) with internal combustion engines (ICE) (230) which have exhaust system provided with particulate filter (261). Fuel is fed to exhaust system through injector (255). In this process, it is determined whether V target operating condition has been achieved in which risk of fuel accumulation in exhaust system is increased. If V target operating condition is achieved countermeasures are taken against fuel accumulation in exhaust system. Particulate filter (261) is provided with temperature sensor (275). Exhaust gas mass flow rate sensor (245) is also accommodated in exhaust system.EFFECT: better V performance.18 cl, 5 dwg
